We have recently installed functionality for the Tapatalk App! This is a fantastic app which enables you to use the forum via the app. The great thing about this is you get push notifications! Not just an email or an on site notification but a real push notification to your phone as things happen like a reply to your post or a post you get tagged in or new messages. This is a great app that will enable you to keep up to date with the forum and be more involved with the community as a whole!

That is a very generic error. Since you are using the default PHP mail server you would have to contact your web host to check the mail configuration in PHP and pull the mail logs. Or you can specify your own SMTP server if you have one available:

Admin CP -> Home -> Options -> Email Options -> Email Transport Method
